Patented Apr. 26, 1938 UNITED STATES OFFICE 4 EGG oan'ron David H. Shapiro, Montreal, Quebec, Canada Application May 17, 1934, Serial No. 726,016 4 Claims. (01. 229-29) ing the body of the box, and partitions swingably connected with the blanks, the blanks being movable relatively longitudinally when in coll lapsed position, at least one of the-blanks serving as a cover for the box.

It is another object of this invention to provide a.container having a collapsible body and interior cells constructed of individual 'fillers.

It is another object of this invention to provide a container having the collapsible body in two pieces, so as to permit the center portions of each to be moved toward the outer portion when collapsing of the box is desired, the one complete portion in this case swinging toward the one side.

It is a further object of this invention to provide a collapsible egg box comprising two blanks, each blank being foldable to provide an outer and an inner wall superimposable thereupon, and partitions swingably connected to the outer walls and projecting through the inner walls, the inner walls adapted to be swung together to provide spaces between a respective inner and i; outer wall for the reception of eggs, the partitions having slots for locking engagement of the inner walls therewith when the box is in operable position. i

It is another object of this invention to make a collapsible container of such construction, that it can be assembled in the very shortest possible ,time. f

It is a further object of this invention to provide a collapsible container with outside lips d tures of construction, combination of parts and in the unique relations of the members and in the relative proportioning and disposition thereof; all as more completely outlined herein.

To enable others skilledin the art so fully to 50 comprehend the underlying'ieatures thereof that the numerous they may embodyathe same by modifications in structure and relation contemplated by this invention, drawings depicting preferred and 'modified'iorms have been annexed as 55 a part of this disclosure, and insuch drawings,

like characters of reference denote corresponding parts through all the views, of which:

Fig. 1 is a plan view of the blank forming the rear portion of the container.

Fig. 2 is a plan view of the blank forming the front of the container.

Fig. 3 is a. plan view of one of the spacers.

Fig. 4 is a plan view of the container in collapsed form.

Fig. 5 is a perspective view of one embodiment of the invention with one large cover.

of the outer. casing is formed from one blank H and the spacers formed from a blank I2. The cover portion l3 has a front flap I 4. This flap it is provided with notches l5 which engage with the partitions or spacers l3 in the closed position.

Flap M folds downward along score line l6. Score lines l'l, I8, l and 20 divide the rest of the rear portion into parts 2!, 22, 23 and 24. Part 2! is the straight rear wall, 22 and 23 are the inclined portionsagainst which the egg rests, while portion 24 isthe upright center wall. Fig.

5 illustrates this very plainly. The front portion H is divided into four parts, 25, 26, 21 and 28 by score lines 29, 30 and 3!. Parts 2i and 28 are provided with short straight slots 32, having an inclined portion 32'. Slots 33 are longer and extend over two parts in both front and rear 2 3. Slots 32 receive the ear projection 36 of spacer l2 while slot 38 permits the center por tion 35 of the spacer l2 to pass through. Notches 36 in the spacer l2 receive and hold the score lines is and 30, respectively. In the collapsed position, as shown in Fig. 4, the lip 31 of notch 38' grips edge 39 of the 'part 25, avoiding thedown form the partitions may be held spaced apart in a fixture and the front and rear blanks or portions ii, iii assembled thereon, but in their .collapsed or folded condition as indicated in Fig.

4. Then the said portions or blanks II, III are moved relatively longitudinally while still in their.

folded condition, at the same time the partitions 55.

portions, namely, 25 and 26 as well as 23 and 35 l2 being swingably carried longitudinally therewith, and the lip 31 is made to grip edge 39, thus keeping the box in its knock-down form.

To collapse the box from its operable position shown in Figure 5, center wall 24 is moved 'tcwards rear wall 2| and center wall 25 is moved forward towards front wall 28, until the center walls respectively touch the outside walls, after which it is very easy to swing the rear and front portions 2| and 28 longitudinally into position as shown in Figure 4, using the tabs 34 of partitions or spacers l3 as pivots. Tabs 34 also act as spacers between adjacent boxes when packed for shipment.

To assemble the device as an egg box, or other merchandise carrier, the part v25 is released from lip 31 and the blanks I0, ll moved relatively longitudinally until the partitions are at right angles thereto. The inner walls 24, 25 are then moved towards each other and made to lockingly engage with the partitions, the walls, at their slotted ends seating within the notches or slots for that purpose.

It is believed from the above description that those skilled in the art will have no difliculty in understanding the construction, the method of use and operation of the device herein disclosed and a. detailed discussion thereof is unnecessary.-

The invention is of simple and practical con- 1 struction and is adapted to accomplish among others all of the objects and advantages herein set forth.

Without further analysis, the foregoing will so fully reveal the gist of this invention that others can "by applying current knowledge readily adapt.

it for various applications without omitting certain features, that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalency of the following, claims.

What is claimed is:

1. A collapsible box comprising two blanks, each blank foldable to provide an inner wall constituting a central longitudinal partition and an outer wall, and spaced transverse partitions swingably connected to the outer walls, the inner walls having slots therein through which the transverse partitions extend, said slots being of sufiicient length to permit abutment of said inner walls against the inner. surfaces of saidouter walls, respectively, and to permit swinging of said inner walls toward each other to provide spaces inner walls towards each other to provide spaces 1 between a respective inner and outer wall for the reception of articles between said transverse partitions, said transverse partitions having slots for locking engagement of said inner walls therewith when the box is in operable position.

3. A collapsible box comprising two blanks, each blank foldable to provide an inner wall constituting a central longitudinal partition and an outer wall, and spaced transverse partitions swingably connected to the outer walls, the inner walls having slots therein through which the transverse partitions extend, said slots being of sufficient length to permit abutment of said inner walls against the inner surfaces of said outer walls respectively, and to permit swinging of said inner walls towards each other to provide spaces between a respective inner and outer. wall for the reception of articles between said transverse partitions, at least one of the blanks having an extension to provide a cover for the box.

4. A collapsible box comprising two blanks, each blank foldable to provide an inner wall constituting a central longitudinal partition and an outer wall, and spaced transverse partitions swingably connected to the outer walls, the inner walls having slots therein through which the transverse partitions extend, said slots being of sufficient length to permit abutment of 'said inner walls against the inner surfaces of said outer walls respectively, and to permit swinging of said inner walls towards each other to provide spaces between a respective inner and outer wall for the reception of articles between said transverse partitions, at least one of the blanks having an extension to provide a? cover for the box, said partitions having slots for locking engagement of said inner walls therewith and said cover having slots for locking engagement thereof with said partitions. i 1 DAVID H.
